I had the same experience with the patch. I was prescribed it the night before I had surgery and the next day I felt like I was falling over and I had blurry vision. Had to take that thing off right away. For cruising, I prefer Bonine (I use a bottle of generic meclizine from Costco). Me and my family take it a couple days prior to vacation and always at night so we can sleep off any drowsiness.I get sea sick backing out of the driveway. I used the patch for years for cruises and long flights. The problem was that while I didn’t feel motion sickness, it messed with both my vision and equilibrium. Then when I took it off I got some strange rebound effects. I started trying the Bonine and it works well for me.
